I have been having the following problem in build 693 and 694:
Sometimes (I can't regenerate it completely) when I undo actions as simple
as a tab character or a paste the file scrolls to the top.
I tried to come up with a definite way to create that but with no success. I
just had that after pressing tab and then undo. The first time it happened,
second and third it didn't.
Anyone else experiencing this so that we can find how to do it every time
(for a more efficient bug filing)?
